German architect Han Slawik created his Homebox design based on the shipping container building model, taking into consideration the ease of transport, universal dimensions and general usefulness of shipping containers. However, the Homebox is not made from an actual steel shipping container. Slawik simply took all the best parts of shipping container architecture and modified it to be easier to build and maintain. Modification of steel structures during the building process, as well as the subsequent repair and maintenance is costly, which is one of the drawbacks of building homes from shipping containers.
